ToaZZ whom it may concern.-

Be it known that I, VVILLIAM W. COREY, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Hy.- drants, of which the following is a specification.

This invention relates to a hydrant which has a drip-outlet through the bottom, which-is closed when the main valve is opened and is opened when the main valve is closed forthe escape of water remaining in the case and stand-pipe after the main valve has been closed.

illustrated has a case which is adapted to be The object of this invention is to provide a very simple and cheap construction whereby the main Valve is easily opened and closed by a powerful mechanism and the drip-valve, which is simple in construction and durable in use, is positively opened and closed by a simple and cheap mechanism. f

The embodiment of the invention that is connected with a water-main and with a standpipe and has a port which is adapted to be opened and closed by a swinging valve that is oscillated by'the movement of a nut up and down a thread on the spindle, which is supported by a block that is loosely held in the case and that guides the drip-valve stem, which is also moved up and down by a nut that fits a thread on the spindle, so that when the main valve is closed the drip-valve is opened and when the main valve is opened the drip- Valve is quickly closed, the spindle, main valve, block, and drip-valve being removable together from the case, ifit is desired to renew or repair the seats or faces of either of the valves.

Figure l of the accompanying drawings shows a central section of the case of a hydrant that embodies this invention with the main valve opened and the drip-valve closed.

wall near the bottom of the case.

,ter which flows through from the main is di rected upwardly toward the stand-pipe.

The main valve 5 has an arm 6, that is hinged to a block 7, so that 'the valve :may be swung against the inclined seat to close the port or drawn back from the inclined seat so it will not interfere with the flow ofwater from the port to the stand-pipe.

The block 7 has wings 8, that are adaptedto restupon lugs 9, that extend from the back The block also has a forwardly-extending tubular part 10, that fits into the upper end of the lining 11 of the drip-outlet 12. The back of the block bears against the back wall of the case as the wings rest upon the lugs, and. the forwardlyextending tubular portion projects intothe drip-opening and prevents theblock from turning sidewise out of place. Openings 13 are made through the side wall of the tubular projecting portion of the block for the outflow of drip-water- Thelower end of the spindlel t' restsin a socket in the upper end of the block. This spindle has a coarse thread 15, upon which. moves a nut 16, that is connected by a link17 with the back of the main valve. When the spindle is turned in one direction, this nut is lowered and the main valve is moved to its seat. When the spindle is turned in the opposite direction, thenut is raised and the main valve is drawn back from its seat against the spindle. All downward thrust upon the block incident to the closing-of the main valve is sustained by the lugs that project from the back wall near I The spindle also hasa fine thread 18, on which moves a nut 19, that is fastened to the dripvalve stem 20. This stem extends down through an opening in a lug 21, that projects outwardly from the upper end of the block and through an opening in the tubular forward extension of the block. Secured to the lower end of this stem is an upwardly-opening cup-packing 22. This packing is shaped to tightly fit the reduced section of the lining to the drip-opening. When the spindle is turned to open the main valve, the drip-valve packing is drawn upwardly from the enlarged section of the lining of the drip-opening into the reduced section, so as to tightly close the drip-opening. The tightness of this packing is augmented by the action of the water-pressure against the sides of the packing. When the spindle is turned for closing the main valve,

the drip-valve is moved downwardly, and just as the main valve is closed the drip-valve packing passes irom the reduced section to the enlarged section of the lining to the dripopening. The main valve,the drip-valve, and the supporting-block are all removed together when the spindle is lifted out of the case and of course all are set together. No special fitting is required for these parts, which are simple to construct, and all the parts are positively held against such yielding as would cause binding when the main valve is opened and closed. A drip-valve of approved form is connected in a simple and cheap manner with the spindle, so that both valves must operate together in a positive manner, and the block which supports the spindle and the main valve and guides the drip-valve is firmly held in position in a simple manner.

The invention claimed is 1. A hydrant having a main valve adapted to open and close a port part way up the case, a drip-valve adapted to open and close an opening through the bottom of the case, a block loosely held near the bottom of the case,a spindle with two threads supported by the block, a nut movable on the upper thread and connected with the main valve, and a nut movable on the lower thread and connected with the drip-valve, substantially as specified.

2. A hydrant having an inlet-port part way up the case, adrip-opening at the bottom of the case, a block loosely supported near the bottom of the case and having a portion that extends into the drip-opening, a spindle with two threads loosely supported by the block, a main valve hinged to the block, a nut movable on the upper thread of the spindle, a link connecting the nut on the upper thread with the main valve, a drip-valve movable in the drip-opening and having a stem extending through a portion of the block, and a nut movable on the lower thread of the spindle and connected with the drip-valve stem, substantially as specified.

3. A hydrant having an inlet-port part way up the case, a drip-opening through the bottom of the case, a block loosely supported near the bottom of the case and having a forwardly-extending portion that enters the drip-opening, a spindle with two threads supported by the block, a valve hinged to the block, a nut movable on the upper thread of the spindle, a link connecting the nut on the upper thread with the back of the main valve, a drip-valve movable in the drip-opening, anut movable on the.

lower thread of the spindle, and a valve-stem connecting the nut movable on the lower thread with the drip-valve and extending through the forwardly-extending portion of the block, substantially as specified.

4. A hydrant having a main valve adapted to open and close a port, a drip-valve adapted to open and close an opening, a block held near the bottom of the case, a spindle with two threads supported by the block, a nut movable on one thread and connected with the 'main valve, and a nut movable on the other thread and connected with the drip-valve, substantially as specified.
